Suspect Is Hatless / Anime & Manga

• In Black Lagoon, the L'homme Sombre arc kicks off with five women searching Roanapur for a tall black man. While that would be unusual in most of Thailand, Roanapur is a Wretched Hive attracting all sorts of criminals and within a couple days, they've already questioned at least six such men.
• In one Case Closed case, the police are trying to apprehend a criminal and catch three suspects. The case seems ridiculously easy when they find three eyewitnesses... but then each of those witnesses give vague descriptions (that the criminal was wearing sunglasses, that the criminal was very tall, and that the criminal was an old woman) and none of those traits match any of the suspects. The police eventually have to figure out what conditions took place to cause each of the eyewitnesses to see the traits they saw, and which suspect all three applied to.
• Date A Live: Origami Tobiichi asks Tohka Yatogami to describe the flame-wielding spirit she witnessed. Tohka says she was red and had lots of fire, causing Origami to call her useless.
• In one chapter of Dragon Half, Rosario and Vina independently summon up monsters and send them to kill Mink, describing her as having horns, wings, and a tail. Since both monsters also meet this description, they end up killing each other before running into Mink.
• One of the powers of Assassin of Black (Jack the Ripper) in Fate/Apocrypha is to invoke this. Anyone who fights Assassin and survives the fight quickly forgets all details of their opponent, so they cannot describe Assassin to anyone else, or recognize Assassin should their paths cross again. This stems from the fact that the powers of Servants are derived from their legends, and a key part of Jack the Ripper's legend is the fact that Jack was never conclusively identified.
• In one Mobile Police Patlabor: The Early Days OVA centers around the men searching for a bomber in a public bathhouse, with the only information they had to identify the suspect being a description of an armpit. The gang goes through a number of crazy hijinks trying to examine the armpits of every man washing up, which ultimately starts a huge brawl. And in the end in turned out to be for nothing, as the perp was female, and SV2 had sent the only female member present to report in to headquarters, leaving nobody to search the women's side of the baths.
• In Sekirei, Benitsubasa calls the Izumo Inn and demands to speak to the "big-breasted woman". Among the 108 Sekirei, there's maybe ten who don't fit that description and half those are men or children.
• The first episode of Trigun has the insurance girls and several groups of bounty hunters looking for Vash the Stampede. Each of them is using a different description of Vash that is technically accurate, but is also vague enough that it also describes one of the other bounty hunters ("blonde man with red coat and big gun^note Vash's Hand Cannon while the bounty hunter wields a rifle"). Confusion ensues.
